Global Distribution of Fe K alpha Lines in the Galactic Center Region Observed with the Suzaku Satellite
Galaxy: Center—Inter stellar medium— X-ray spectra
2011/7/15
We have surveyed spatial profiles of the Fe K$\alpha$ lines in the Galactic center diffuse X-rays (GCDX), including the transient region from the GCDX to the Galactic ridge X-ray emission (GRXE), with...
The Mid-Infrared High-Ionization Lines from Active Galactic Nuclei and Star-Forming Galaxies
The Mid-Infrared High-Ionization Lines Active Galactic Nuclei Star-Forming Galaxies
2010/11/30
We used Spitzer/IRS spectroscopic data on 426 galaxies including quasars, Seyferts, LINER and HII galaxies to investigate the relationship among the mid-IR emission lines. There is a tight linear corr...
Strong [O III] and [N II] emission lines in globular clusters from photoionized R Corona Borealis star winds
emission lines globular clusters
2010/11/30
The globular cluster X-ray source CXO J033831.8-352604 in NGC 1399 has recently been found to show strong emission lines of [O III] and [N II] in its optical spectrum in addition to ultraluminous X-ra...
Probing Intermediate Mass Black Holes With Optical Emission Lines from Tidally Disrupted White Dwarfs
Probing Intermediate Mass Black Holes Optical Emission Lines
2010/11/30
We calculate the emission line spectrum produced by the debris released when a white dwarf (WD) is tidally disrupted by an intermediate-mass black hole (IMBH; $M\sim 10^{2}-10^{5}\msun$) and we explor...
Spectral imaging of the Sagittarius B2 region in multiple 7-mm molecular lines
Galaxy Astrophysics (astro-ph.GA)
2010/10/12
We have undertaken a spectral-line imaging survey of a 6 x 6 arcmin^2 area around Sgr B2 near the centre of the Galaxy, in the range from 30 to 50 GHz, using the Mopra telescope. The spatial resolutio...
High-resolution mapping of the physical conditions in two nearby active galaxies based on 12CO(1-0), (2-1) and (3-2) lines
Galaxy Astrophysics (astro-ph.GA)
2010/10/11
We present a detailed analysis of high resolution observations of the three lowest CO transitions in two nearby active galaxies, NGC4569 and NGC4826. The CO(1-0) and (2-1) lines were observed with the...
The Hanle Effect as a Diagnostic of Magnetic Fields in Stellar Envelopes. V. Thin Lines from Keplerian Disks
Solar and Stellar Astrophysics (astro-ph.SR)
2010/10/10
This paper focuses on the polarized profiles of resonance scattering lines that form in magnetized disks. Optically thin lines from Keplerian planar disks are considered. Model line profiles are calcu...
